In small mixing bowl combine the flour, baking powder, baking soda, and salt. Set aside.
In a large mixer bowl add ½ cup sugar and butter. Beat until creamy (1 minute). Add the egg, sour cream, orange juice, orange zest, and vanilla extract. Continue beating, scraping the bowl often, until creamy (1 minute).
Pour the flour mixture into the sour cream mixture and mix just until moistened. Gently stir in the cranberries and the pecans.
Spoon evenly into 3 greased 3 x 5-inch pans. Sprinkle the tops evenly with the remaining 1 tablespoon of sugar.
Bake for 35-40 minutes or until a toothpick inserted in the center comes out clean. Cool for 10 minutes. Turn bread out of the pans. Cut into slices. Cover leftovers.
